Several of the program’s tools, too, fall short of Adobe's state-of-the-art software. It’s feature-packed and powerful, but some operations are still slow and the user interface still lacks some friendliness found in competitors. The latest version of this photo editing software adds hardware acceleration for improved performance on Windows, linked layers, astrophotography stacking, and custom interface presets. Serif’s low, non-subscription pricing is no doubt a factor for some users. The Affinity apps are also available for Windows, and the company is attempting to make inroads on Adobe's firm grip on the media and design software industry. Its Affinity line, which started with Mac-only apps in 2015, even garnered an Apple Mac App of the Year award that year.
